Summary

  • ARCEP’s October draft says current recurring tariffs on slightly more than half of public-initiative FttH networks sit below costs calculated by its updated operating model. Most indicated increases for those networks are €0.50–€2 per active access per month.
  • The proposed monthly reference is non-binding and meant to inform network-by-network negotiation. It does not settle contract terms, consumer prices, the cost of resilience or every investment needed to keep a fibre network sustainable.

A rural fibre line can be open to competing service providers and still be hard to keep in working order. The recurring wholesale payment that supports access may not match the cost of repairing faults, inspecting cabinets, managing orders or renting civil infrastructure. France’s telecom regulator is now asking the parties to make that mismatch measurable.

On 15 October, ARCEP published a revised operating-cost model and draft tariff guidance for publicly initiated fibre-to-the-home (FttH) networks. Its simulations, based on information supplied by infrastructure operators, put current recurring tariffs below modelled operational-maintenance costs on a little more than half of the covered networks. On most of those, the agency estimates that €0.50 to €2 more per active line each month would cover the modelled gap. That is an estimate for affected networks, not a price rise already agreed or a national tariff order.

The distinction matters because a wholesale tariff has more than one job. A local infrastructure operator builds and runs the passive network; commercial operators buy access and sell retail services. Some operators co-finance construction and receive long-lived usage rights. Others rent access by the line. The draft treats co-financing rights as support for initial construction, not as a payment for ongoing maintenance. Recurring co-financing charges and part of rental fees, depending on the product, are the main channels for recovering operating costs. A line price can also include a component for the original build.

Comparing the whole charge with maintenance cost alone can therefore mix different obligations.

ARCEP’s proposed reference works from a network’s own characteristics rather than a single national cost per subscriber. It estimates annual operating costs as fibre replaces fixed lines, adds some costs not already recovered through separate billing or co-financing, divides by projected active lines, then adjusts for the average over 25 years and higher unit costs in the early years. The method also adds Orange local-loop civil-engineering rental and a financing component for initial construction. It is designed to help determine whether a contract’s recurring payment leaves a maintenance gap and to give the parties a common starting point.

The updated model incorporates feedback from an earlier consultation that received 36 contributions. ARCEP reduced its estimate of corrective maintenance visits to better match observations from operators that supplied data, while raising some support-cost and information-system assumptions. In its companion document, preventive maintenance costs include annual visits to network mutualisation points, conformity work on a portion of those points, and audits at branch points. These are model inputs, not an audit of each network’s actual expenses. Network-specific operating data still matter.

The model is deliberately bounded. It covers preventive and corrective maintenance, wholesale commercialisation, certain civil-engineering use, taxes and occupation charges, shared corporate costs and extensions for new buildings. It does not model undergrounding or diversion work: ARCEP says those activities depend on local decisions and can vary by more than tenfold between territories. The draft also excludes future investments beyond maintenance, including upgrades intended to strengthen resilience. Complex connections and unfinished rollout are separate problems.

An operational-cost benchmark cannot by itself finance every improvement that an ageing or exposed network may need.

Nor does the draft mandate that parties adopt ARCEP’s calculation. The proposed guidance is explicitly non-binding. The monthly minimum is a reference for identifying a shortfall, not a replacement for contract negotiation or a figure to paste into every agreement. The parties may use another method if they can justify it under the applicable principles of relevance and objectivity. Whether a particular tariff or proposed adjustment is reasonable remains a case-specific question.

The open consultation runs until 16 November 2026 at 18:00 Paris time. ARCEP particularly invites comments on how the minimum recurring charge should be calculated; other parts of the guidance had already been consulted. The result will show whether the regulator changes the model or the bargaining reference before applying it. This discussion arrives after more than twelve years of France’s national fibre plan: as of 30 June, 95.3% of premises were connectable to fibre and 85% of fixed broadband subscriptions used it. Those national numbers describe reach and adoption, not whether each rural network earns enough to maintain service.

For now, the proposal makes an operating deficit legible but does not allocate it. Whether cost recovery falls on wholesale customers, is offset by existing contract components, or leads to some later retail-price change depends on the contract and the negotiation. The next test is whether a shared estimate produces transparent amendments while preserving the open access that public funding was meant to support.
